ELI5: Explain Like I'm 5

Vocal learning

Vocal learning is when an animal learns how to make sounds, like music or speaking. Humans can do this, and so can some other animals, like birds, dolphins, and whales. When a baby is born, it has to learn how to make sounds. We learn by listening to others. For example, babies start by copying the sounds from their parents or family. As they get older, they can make more and more complex sounds, like words and sentences.
